I am here at CERN and the Large Hadron Collider experiment in Geneva. For physics there is surely nothing like this anywhere on the planet. Underlying the LHC work is a worldwide "grid" of incredible computational power, the origins of which can be tied to the very spot where the photo accompanying this post was taken. The plaque is on the door of the CERN office where Tim Berners-Lee and Robert Cailliau developed what we now know as the World Wide Web. In fact, the original two web servers, developed to facilitate data sharing from particle physics experiments, are still here.

The electric car maker takes a hit as it talks layoffs and cutbacks, in an attempt at a figment of profitability. Musk says it will be a difficult year.

BTW, if you get a broken window in your Tesla, you could be looking at a couple of months before you get a replacement. And then there is the problem of the rear side window being broken. Apparently thieves use that to get through to the trunk and no alarm is triggered.

Kim Nilsson: Ah, so now those who have long tried to short the Tesla stock is finally making any money. Vultures.

Wolfgang Rupprecht: Great even-handed summary. Most popular press articles about quantum computing seem to hint that quantum computers, will magically find any answer instantly. All the scholarly papers i've seen talk about different iterative methods for quantum computers that will cut the number of iterations down from the number required on traditional computers. The ones I could understand only cut the search space down to half the number of bits. Problems that took 2^256 iterations on traditional computers would only take 2^128 iterations on a quantum computer. That is a vast improvement, but far from instantaneous.

Pierre Renaud: +Peter Vogel, not sure what to do next. I have a different assignment this year and teach about 175 elementary students (phys ed, health, dance). So, I didn't bother setting up classes. However, I still teach several students from my previous years. So, these parents are still reaching me using their unique Remind number. I feel that if I have to ask parents to install the app or enable email notifications, I might as well just use Gmail. I have a Google Voice number I could share, but I'm afraid it would cost them money to sent their messages to a US number. Share my personal number? Probably not a good idea. Frustrating...

Peter Vogel: It is a mess. I am talking about this on radio today on Corus stations.
